STOP-COCK.

SPECIFICATION forming part of Letters '.'atent No. 417,785, dated December 24, 1889,

Application filed May 7, 1889. Serial No. 309,848. (No model-l To LZZ whom t may concern:

Be it known that I, J ULIUS I-IELTZLE, a cit-izen of the United States, residing at-St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Stop-Cocks,

of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a means of automatically draining deliverypipes for wash-basins, bath-tubs, sinks, dac., said means to act in connection with a stopcock supplying said basin. To this end I have constructed my device in the manner described in the following` specification, and with such novel features as will be found set forth in the claims at the end of the same.

In the drawings, Figure l is a side elevation of my device,the plunger and its casing being shown in vertical section. Fig. 2 is a side elevation of my 'device in position, showing its connection with delivery stop-cock and its preferred position with relation to the basin.

Like letters of reference indicate like parts in bot-h figures of the drawings.

A is a cylindrical casing provided with two opposite ports A and A2, the former being higher than the latter. These ports are interiorly screw-threaded for the insertion of the pipes B and C, for supply and outlet, respectively. The top of the cylinder is closed by a cap screwed or otherwise fastened thereon, said cap being apertured at A4 for the passage of the plunger. The supply-pipe B is connected .with the higher port A', while the delivery-pipe C is connected with the lower port. As seen in Fig. 2, the casing is placed, preferably, beneath the level of the basin or sink, and the supply-pipeB rises to a considerable elevation above the level of the delivery-port.

D is astandard, either connected to the case A, as shown in Fig. 2, or separate therefrom. To the top of this standard is pivoted, as at D', a walking-beam D2, to one end of which is attached a closing-rod F, having a cam F' at the top thereof, preferably formed, as shown in Fig. 2,by curving the upper end of the rod. rIlhis rod is actuated by contact with the rear end of the stop-cock handle E, and attached below this rod and at the under side of the walking-beam is the spring F2, which acts to return the rod to its lowest posit-ion, thus closing the inlet-valve. At the end of the walking-beam opposite to that at which the closing-rod is pivoted there is pivotally attached a link I-I, to the other end of which is pivoted the top of the plunger-rod I.

IVithin the casing A is a plunger J, perforated, as shown at K, with a passage having one opening higher than the other, and so formed that its upper opening will register with the port A' at the same time that the lower opening registers with A2; The top an d bottom of this plunger are preferablybeveled, as shown, for the reception of leather washers J', which are held on by means of metal washers J2, held in place and adjusted at will by means of nuts J 3, screwed onto the plunger-rod I and the plunger-tip I', respectively.

Fig. l shows the plunger in its closed position, the sides thereof entirely stopping the V entrance-pipe B, while the opening of the delivery-pipe C is left free, thus allowing ofthe drainage of the standing pipe C through the opening L at the bottom of the casing, this opening communicating with an open sink or waste-pipe, as desired.

The plunger need not necessarily be constructed as above described, but may consist instead of a central spindle, (shown in dotted lines in Fig. 1,) and provided with water-tight heads, as therein shown. IVhen thus constructed, the supply-pipe B will never be closed, and there will be a body of water always included between the heads of the plunger, the depression of the plunger merely bringing this body of water into communication with the delivery-pipe C.

Vhichever construction is employed the operation of my device will be as follows: The stock-cock E being turned to the open position, as shown in Fig. 2, its rear end impinges against the concave surface of the closing-rod F, raising the same into the position shown in Fig. 2. The raising of this rod depresses the link Hand through it the plunger J, bringing the opposite openings of the perforation K into position to register with the ports A' and A2. Connection being thus established between these ports, the water is allowed to iow into the basin above. If desired, the rod F may be operated by hand and the faucet or cock E may be dispensed with.

IOO

which shallby any possibility be the occasion j of Waste during the operative action of the valve.

What I claim isl'. A valve-casing having supply and delivery ports, one placed higher than the other, a plunger sliding therein and having an inclined passage, a standard, and a Walkingbeam pivotally connected with said plunger, in combination With a closing-rod pivotally attached to said walking-beam at the end opposite to that of the attachment of the plunger, and a spring attached beneath said wall;- ing-beam near said closing-rod, substantially as specified.

2. A casing provided with a drip-opening, a supply-port, and a deliveryport, one higher than the other, and a plunger sliding in said casing and provided with an inclined perfoportion of said delivery-port when in a closed position, substantially as specilied.

3. A casing provided With a Valveless dripopening, a supply-port, and a delivery-port,

one placed higher than the other,in combination with a plunger sliding in said casing and provided With a perforation of the same diameter as said ports, and its openings so disposed as to register simultaneously with said ports, the bottom of said plunger being adapted to rise above a portion of said delivery-port When in a closed position, substantially as specified.

4. A casing provided With a drip-opening, a supply-port, and a delivery-port, a deliverypipe connect-ed to said delivery-port, a plunf ger sliding in said casing and provided With an inclined perforation the ends of which are disposed to register simultaneously With the l, two ports, and a plunger-rod rising' from the ttop of said plunger, in combination With a standard, a Walking-beam pivot-ally attached f at one end to the top of said plunger-rod, a fclosingrod pivotally attached at the other end of said Walking-beam and provided With ta cam at the top thereof, a spring attached to said Walking-beam near said closing-rod,

and a stop-cock adapted to move in a path intersected by the cam on said closing-rod,

substantially as specilied.

In testimony whereof I affix my signature in presence of two witnesses.

ration the ends of which are adapted to register simultaneously with said ports, the bottom of said plunger being adapted to rise above a i JULIUS HELTZLE. Witnesses:
